ELECTRIC HEADLIGHT FOR VEHICLES.

Application filed October 14, 1921. Serial No. 507,702

To all whom it may concern:

Be it known that I, KARL KLEINERT, a citizen of Germany, residing at Stuttgart, Germany, have invented certain new and useful Improvements in Electric Headlights for Vehicles, of. which the following 1s a specification.

This invention relates to electric head lights forvehicles wherein each 1i ht carries a plurality of lamps, for examp e, a main lamp and one or more auxiliary lamps which are carried by the reflector and inserted from the rear into the latter. In the ordinary head lights of this type each lamp is fixed independently in the reflector, either by its holder being laced in a cover which is inserted from t 0 rear into. a corresponding slot in the reflector, or the socket is directly constructed in the reflector as is frequently the case where so called tubular lamps are 'employed. This arrangement has the disadvantage that in order to be able to remove the lamps from the reflector, the rear side of the latter must be made accessible. This head light casing or swinging it back out of it. In doin this however the lamp sockets are separate from the current leads so that all the lamps of this headlight go out and it is consequently quite dark. It is then of course difiicult, or at least inconvenient, to remove the com aratively small lamps from the reflector and ticularly in the case of lamps whose sockets are constructed in one with the reflector.

In order to avoid this disadvantage, ac-' cording to the present invention the sockets of all the lamps are arranged on a common carrier which is easily releasable and is attached to the reflector from the rear. With this arrangement in order to change the lamps it is only necessary to remove the one carrier from the reflector which can be done without trouble even in darkness, then the carrier with all the lamps can be brought into the light of the other head light and the changing of the lamps can be effected in a convenient manner.v The arran ement according to this invention has the urther advantage that the manufactureof a head light with a plurality of lamps is substantially simplified, on account of the construe-- tion of sockets in one with the sensitive reflector bein avoided.

It is pre erable to form in the reflector separate guide in the reflector. Of course. no

to insert them again par-f 7 separate openings, one for the insertion,

of each lamp, because the reflecting surface is thereby interrupted in a much-lesser degree than where only one opening large enough for the insertion of all the lamps n.-

the reflector is provided. By this arrangement, also, and particularly by the insertion and withdrawal of the lamps from the rear, the possibility of an accidental touching of the mirror surface, and hence the dulling of its polish, b the fingers in the act of inserting and wit drawing the lamps is practically obviated.

In order to make my invention more clear, I refer to the accompanying drawing, in which:

Fig. entire head light.

Fig. 2 shows the crown part of the reflector, and

Fig. 3 a section of the lamp holder.

1 is a vertical axial section of the The reflector a is closed in front by a glass .This has in addition a border or collar ;0

which is inserted in a suitable support g on the reflector. The support q surrounds the opening for the main lamp h and is mounted on the rear side of the reflector. The two openings and g in the reflector a are designed on y of sufficient diameters to permit the insertions therethrough of the lamps h and i, res ectively, and to provide for the location 0 the lamp sockets and holdersin or adjacent the openings as shown in Fig. 1. With such openings, and the arrangement of parts permitting the insertion of the lamps therethrough from the rear of the reflector, the possibility of an accidental touching of the mirror surface of the reflector by the fingers in exchanging or adjusting the lamps in position is practically obviated. The holder m for the tubular lamp a is prolonged all round up to thereflector in order that the opening met The lamp 5 has not however" a at the rear may be entirely closed I ing from the scope of the invention. The

socket 9.

lead connection terminals and the guide con-' tacts for the two lamps h and 11 are mounted on a common insulating piece a" which is connected with the casing e by a earner s in any suitable way. The spring pressure of the contacts t and u prevent the lam holder 0 from slip ing out at the rear of t e guide .5 further security such as a spr ng rest 'v or support on the socket q or the like may however also be provided.

If, for exam le, the main lamp h be burnt out and no ot 181 spare lamp is at hand, it is possible to employ the lamp 2' in place of the lamp h. For this purpose the reflector a is turned on the hinge 01 out of the headlight casing e. The rear of the reflector is then exposed, and the lamp holder 0, together with the two lam s h and z, is withdrawn from the reflector -y a single movement. After the lamp 2; has been changed for the lamp h the lamp holder with its collar p is again inserted in the support 9 whereupon the reflector is swung back into the casing 6.

Having now described my invention, what I desire to secure by Letters Patent of the United States is:

1. An electric headlight for vehicles comprising, in combination, a reflector, a main lamp and an auxiliary lamp, a common holder for mounting both of said lamps within said reflector and with their currentreceiving terminals exposed on said holder, current-supply terminals mounted adjacent the rear Wall of said reflector, and means for detachably mounting said holder in the rear wall of said reflector with said lamp terminals in free contact with said currenttor, a main lamp and an auxiliary lamp, a

incense common holder for mounting both of said as lamps within said reflector with their axes parallel with the major axis of said reflector, and 'means for detachably mounting said holder in the rear wall of said reflector, said means enabling a ready mounting of said or tor, a main lamp and an auxiliary lamp, a a

common holder for mounting both of said lamps within said reflector on spaced axes parallel with the major axis of said reflector and with the current-receiving terminals of said lamp exposed on said holder, currentsupply terminals mounted adjacent the rear wall of said reflector, and means for detachably mounting said holder in the rear wall of said reflector with said lamp terminals in free contact with said currentsupply terminals.

4. An electric headlight for vehicles comprising, in combination, a parabolic reflector, a main lamp and an auxiliary lamp, said reflector having separate openings in its rear wall, one for each of said lamps, of sizes just suficient to permit the insertlon of said lamps therethrough with their axes parallel with the major axis of said reflector, a common holder for said lam s enabling the aforesaid insertion of sai lamp from the rear of said reflector and means for detachably securing said holder on a rear wall of said reflector to removably mount said lamps Within said reflector in their said positions of insertion.

In testimony whereof T have aflixed my slgnature 1n presence of two witnesses.
